I play around with my m340i, with a camera inside the cabin and a gopro suction cupped to the rear bumper to hear what happens when you check the “Iconic Sounds” check box in iDrive 8.
- What I initially heard was a LOT of speaker generated engine noise. It’s pretty obvious at first that the speakers are augmenting the sound in Sport Plus, but what I didn’t initially realize was that all the cool pops and bangs on overrun were also fake!
- A few commenters on the channel pointed out that it does indeed open the valves when you check “Iconic Sounds” so I had to see for myself.
- The end result - yes, the car fakes a lot of noise with the “Iconic Sounds” checkbox checked
- BUT - it also makes more noise and a throatier exhaust note as well.
- And, even though the car pops and bangs inside through the speakers, you do get some pops and bangs after the car warms up from the real exhaust, although they are pretty quiet.
Hope you enjoy hearing what the car sounds like. I’ll do some flyby videos - I’m curious if you can tell what’s going on with a flyby…
The car is totally stock. 2023 BMW m340i LCI.
